Arick Tamso was a male Human doctor living on Balmorra during the Galactic War along with his brother Pol. During the Battle of Balmorra Arick worked along with fellow doctor Tabo on pacifying the Colicoids at the Sundari Research Grounds facility. However, Tabo hoped to use the Colicoids as a weapons and sabotaged the experiments by tampering the suppressive implants and causing the Colicoids to break free, killing the staff. Tabo sealed Arick Tamso and the other survivors in and fled to safety, though before his death Arick managed to make a holorecording that proved Tabo's guilt.
